Recently while looking at Tengraph for potential areas to detect, I have noticed many areas that are completely black. Tengraph identifies these as Mineralisation Zones and according to the legend they are “Areas in which applications of Exploration Licences are restricted to a maximum of 70 blocks”.

I contacted DMP in Perth and was advised that these areas were open to metal detecting. Since either mining or exploration leases surround most of these black areas, I presume it will only be a matter of time before they appear on Tengraph as pending leases.
